Megaturn
From DominionStrategy Wiki
A megaturn strategy is one that eschews buying any Victory cards until one last game-ending turn. In contrast with a typical Big Money strategy, where you buy one Victory card per turn throughout the endgame, a megaturn deck will buy no Victory cards for the first 12-14 turns of the game and then buy enough Victory cards to end the game at some point between turns 14 and 16. Common enablers of mega-turn strategies are King's Court, which super-charges engines, and Bridge, which provides cost reduction and +Buy.
